Dust is a general name for minute solid particles with diameter less than 500 micrometers (otherwise see sand or granulates) and, more generally, for finely divided matter.
The dust which collects in houses is composed of atmospheric dust combined with dust generated by the inhabitants, mostly from sloughed skin cells and fibers from clothing and coverings
